Workshop: ERC20- Overflow Bug

Workshop: ERC20- Overflow Bug

In this webinar, we’ll dive into a recent bug in some ERC20 contracts that allowed attackers to give themselves a huge number of tokens without paying anything. We’ll look at the bug that allowed this to happen, and how we can prevent it. We’ll also exploit the bug ourselves on an existing smart contract, to demonstrate how it is done.
